Try googling polygonum aubertii foliage and look at the images of the leaves of mature plants. You may not see any similarities until your seedlings have developed their true leaves. www.seedman.com has a pretty clear image of mature foliage. I hope this helps!

I have a silver lace vine that I planted about six years ago. Each year it gets more lush. Last August it was beautiful (it goes over an arbor. So far this year I have no life on it at all. I have scrathed some of the branches and they are green. So here it is the second week in June and I still do not see any leaves trying to open up. We did have a cold Spring and even a frost two weeks ago. But not it's hot and humid. Can anyone pleae give me some advie. Thanks
